AIR-SUPPLY APPARATUS FOR SUBMABINE VESSELS.

Specification of Letters Patent.

Patented May 19, 1914.

Application filed February 27, 1914. Serial No. 821,574.

To all whom it may concern:

Be it known that 1, PAUL PARNITZKY, a subject of the King of Hungary,and resident of the city of New York, in the county of New York andState of New York, have invented certain new and useful Improvements inAir-Supply Apparatus for Submarine Vessels, of which the following is aspecification.

The present invention relates to a submarine boat, and more particularlyto means which insures a constant circulation of pure air in the livingcompartments of the vessel.

One of the objects of the present invention is to produce an air supplyapparatus for submarine vessels which is simple in construction,efficient in operation, and that will permit the vessel to remainsubmerged for any desired time.

Another object of the invention is to produce an air supply apparatusthat furnishes air to the vessel by the action of the water in which itis submerged, so that the vessel need not carry along an air supply oran air refreshing supply.

With these and other objects in view, which will more fully appear asthe nature of the invention is better understood, the same consists inthe combination, arrangement and construction of parts hereinafter fullydescribed, pointed out in the appended claims and illustrated in theaccompanying drawings, it being understood that many changes may be madein the size and proportion of the several parts and details ofconstruction Within the scope of the appended claims without departingfrom the spirit or sacrificing any of the advantages of the invention.

One of the many possible embodiments of the invention is illustrated inthe accompanying drawing, which illustrates a side elevation, partly insection, of a submarine boat constructed in accordance with the presentinvention.

The vessel is constructed on the theory that sea water contains acertain amount of air, which can be liberated from the water when thelatter is allowed to enter a vacuum or partial vacuum in the form of aspray.

Referring now more particularly to the drawings, the numeral 1 indicatesthe body or hull of the vessel and 2 the conning tower. The hull may beof any suitable construction. The other parts of the vessel, which donot relate directly to this invention, are

not described herein. The hull is divided by partitions 3 and 4 intothree sections or compartments, that is a middle section 5, that formsthe living compartments, a front or bow section 6 and a rear orsternsection 7. The front and rear sections communicate through a tube 8,that is disposed, preferably, immediately above the keel of the boat. Tothe front or how compartment 6 leads a tube 9, having a flaring mouth 10and terminating in a sprinkler 11 at its inner end, which is disposedwithin the said compartment. An opening 12 is provided 1n the partition3 for accommodating a fan or similar device 13, that is mounted upon ashaft 14:, the latter being actuated in any suitable manner by theengine of the boat. The fan 13 is of the suction type, or moreparticularly it creates a partial vacuum in the compartment 6. Withinthe rear or stern compartment 7 is disposed a water pump 15, its suctionpipe 16 terminating a suitable distance above the bottom of the saidcompartment, and its pressure pipe 17 leading through the wall thereof.It is obvious that the pump 15 may be disposed within the compartment 5of the boat without departing from the invention. In the partition 4 isformed an opening 18, in which is located a fan 19, its shaft 20 beingactuated in any suitable manner. The fan 19 is of the pressure type, itcausing air to be delivered from the compartment 5 into the compartment7. The exhaust pipe 21 of the motor of the boat leads into thecompartment 7.

It is to be observed that the capacity of the pump 15 is such that itprevents the water from rising in the bow compartment 6 a substantialdistance above the upper level of the connecting tube 8.

The operation of the device is as follows: The pump 15, and the fans 13and 19 are put into operation before the vessel is submerged. As soon asthe level of the water rises above the flaring mouth 10 of the tube 9,water enters the latter. The water so entering is sprayed as it is beingdischarged through the sprinkler 11 into the partial vacuum which existsin the bow compartment 6. This partial vacuum is created due to the factthat the fan 13 is continuously rotated, and thus causes air to movefrom the compartment 6 into the living compartment The air which iscontained in the water is liberated due to the partial vacuum existingin the compartment 6, and is then sucked by the fan 13 into thecompartment 5. The waterv that enters the compartment 6 flows throughthe tube 8 into the compartment 7 from which it is discharged throughthe pump 1-5. The fan 19 causes a flow of air into the compartment 7,whence it is caused, together with the products of combustion that enterthe said compartment through the exhaust pipe 21, to flow through thepump tothe exterior of the vessel. It is to be noted that a valve maybemounted in the pipe 9 to regulate the flow of water therethrough or toshut it off altogether, if necessary.

What I claim is 1. In a submarine boat, the combination with a bodysection, of two interconnected compartments, a water supply pipe leadingto one of said end compartments provided with a sprinkler located withinsaid coinpartment, a water' discharge pipe leading from the other one ofsaid compartments, means for forcing the water from the last namedcompartment through said discharge pipe to the exterior of the boat, andmeans for causing air to flow from said first named compartment to saidbody section and from the latter to said second named compartment.

- 2. In a submarine boat, the combination with a body section, of a bowcompartment, a stern, compartment connected with said bow compartment, awater supply pipe leading to said bow compartment provided with asprinkler located therein, a water'discharge pipe leading from saidstern compartment, a pump for discharging the water from said howcompartment through said discharge pipe, and means for causing air toflow from said bow compartment into said body section and from thelatter to said stern compartment.
